Patent GB-1379631-A (GB)
Title: Energy conversion system
IPC: F03B17/00
Filed: 1972-01-10
Abstract: 1379631 Hydraulic power plant R E McALISTER 10 Jan 1972 1083/72 Heading FIT The plant shown in Fig. 1 comprises two vessels 20, 22 which each contain liquid and vapour a liquid or hydraulic motor 30', a reservoir 24 and a boiler 26. Assuming the vessel 22 to be full of water, steam under pressure generated in the boiler 26 is directed through valve 28 to the vessel 22 whereby water is forced out of the vessel and flows through check-valve 32 to the motor 30' which is thus driven, the water discharging from the motor through check-valve 34 into the vessel 20 which at this phase of operation is vented to atmosphere through vent 40. Thus as the vessel 22 is emptied so the vessel 20 is filled. When the vessel 22 is emptied, the valve 28 is operated so that steam under pressure is now directed into the vessel 20 and water is forced therefrom through check-valve 36 to the motor thence through check-valve 38 to the vessel 22, the vessel 22 now being vented to atmosphere through vent 42. Some water may pass from the check-valve 32 or 36 to the reservoir. In Fig. 2 (not shown) water passes from the vessels to an alternating type of motor which rotates a shaft in one direction. In Fig. 4 (not shown) water may pass directly from the vessels to the steam generator. In Fig. 5 (not shown), the water is forced into the boiler by means of a tuning fork and horn assembly. In Fig. 7 the fuel such as methane used to fire the vapour generator is also the working fluid - methane from tank 136 enters the system at 138 and passes with methane discharging from the hydraulic motor 134 to the vessel, either 130 or 132, being filled. Some methane being discharged from the vessel 130 or 132 being emptied passes through valve 140 or 142 to the boiler 152 or 150 - the boilers are heated by methane vapour discharged from the vessel 130 or 132 being refilled, the vapour passing through check valve 166 or 164 to a burner 160; an oxidizer from the tank 168 is also passed to the burner 160. Many other embodiments are described.

Title: Improvements relating to the monitoring of radar equipment
IPC: G01S7/40
Filed: 1949-01-14
Abstract: 687,773. Radiolocation. BRITISH THOMSON-HOUSTON CO., Ltd., and MELVILLE, W. S. Jan. 3, 1950 [Jan. 14, 1949], No. 111/49. Class 40 (vii). In a pulse radar system, particularly wherein the cathode-ray display unit is located at a point remote from the transmitter and receiver, a monitor cathode-ray tube TC is provided at the transmitter-receiver location, the time-base for which is derived from a condenser C1 and impedance S in series and charged through a gas-filled valve T which is switched on at the instants of pulse transmission to excite the transmitting magnetron. The potential across the condenser - impedance which decays exponentially through the resistors R 1  and R 2  is applied to the deflection-plates of the cathoderay tube. An integrating circuit R 3 , C 3  smoothes out the peak occurring at the commencement of the sweep waveform due to the impedance S. The sweep waveform amplitude is arranged to be approximately twice that necessary to produce a full-scale deflection on the cathode-ray tube, and to decay to half amplitude in 12.4 microseconds, so that by choosing either the first half or the second half of the sweep waveform the display shows either a range from zero to one nautical mile or a range from one nautical mile to, say, 50 nautical miles.

Abstract: 436,938. Converting. AKT.-GES. BROWN, BOVERI, & CIE, Baden, Switzerland. Jan. 19, 1934, No. 1934. Void [Abridged as open to inspection under Sect. 91 of the Acts, July 20, 1934]. [Class 38 (ii)] Relates to the control of gaseouselectric discharge devices of the kind having grids adapted to permit of an arc at any anode being extinguished by application of negative potential to the corresponding grid while the anode is positive, and consists in applying the control potential through a glow discharge tube or vacuum valve. Fig. 2 shows connections for one anode b of a rectifier, the control grid d being supplied with fixed ignition potentials through resistances r1, r2 and with adjustable extinguishing potentials from a transformer t and source of steady negative potential f through a discharge tube g. In a modification, Fig. 3 (not shown), both the ignition and extinguishing control potentials are adjustable and are supplied to the control grid through discharge tubes. In a further arrangement, Fig. 4, adjustment of the moment of extinction is effected by supplying extinguishing potentials through grid-controlled vacuum valves V1, V2, V3 in the circuits of the control grids d1, d2, d3, and determining the moment at which the valves V1, V2, V3 begin to conduct by varying the bias derived from a potentiometer S applied to their grids. In a modification, Fig. 5 (not shown), both the ignition and extinguishing control potentials are rendered adjustable by being supplied through gridcontrolled vacuum valves. In a further arrangement, Fig. 6, in which the discharge device a operates as an inverter, the ignition and extinguishing potentials for the grids d are derived from condensers c1, c2 and applied through discharge devices V1, V2. In this case control is effected by varying the time constants of the condenser circuits. In all cases, an additional grid e is associated with each anode b and is connected thereto through a resistance. The invention may be applied to discharge devices operating other than as rectifiers or inverters, e.g. discharge devices controlling the field circuit of a generator for regulating voltage.

Title: Roasting process
IPC: C22B1/02
Filed: 1962-01-19
Abstract: A process for roasting iron sulphides, which may be contaminated with copper, nickel or cobalt, to form sulphur dioxide suitable for sulphuric acid production and magnetic capable of being leached to remove the above-mentioned impurities is characterized by reacting the sulphide at 700 DEG  to 900 DEG  C. with 94 to 103% wt. of the oxygen required to oxidize the total sulphide sulphur content to sulphur dioxide and the total iron content to magnetite, thus producing sulphur dioxide substantially free from sulphur trioxide and magnetite substantially free from ferric oxide, separating the product solid and gaseous phases, and cooling the magnetite under non-oxidizing conditions. Preferably, heat is extracted from the reaction and reaction is effected in a bed of the sulphide fluidized by the passage of oxygen therethrough. In specific examples the magnetite thus prepared is leached in the presence of air to remove copper by (1) dilute sulphuric acid, (2) aqueous ferric sulphate containing sulphuric acid, (3) ammoniacal ammonium carbonate, (4) ammoniacal ammonium carbonate containing potassium persulphate, (5) aqueous potassium persulphate containing sulphuric acid, and (6) cupric ammonium carbonate solution followed by ammoniacal ammonium carbonate.
